Nick Stone

1993: Under deep cover, Nick Stone and a specialist surveillance team have spent weeks in the jungles and city streets of Colombia. Their mission: to locate the boss of the world's most murderous drugs cartel - and terminate him with extreme prejudice. Now they can strike. But to get close enough to fire the fatal shot, Nick must reveal his face. It's a risk he's willing to take - since only the man who is about to die will see him.

When a young trooper is shot in the head at the Regiment’s renowned Killing House, Nick Stone is perfectly qualified to investigate the mysterious circumstances more deeply. He has just returned from Moscow – still trying to come to terms with the fact that his girlfriend and baby son are safer there without him – so combines an unrivalled understanding of the Special Forces landscape with a detachment that should allow him to remain in cover.

Ex-deniable operator Nick Stone has spent a lifetime in harm's way - but when someone he cares for very deeply is murdered in cold blood, he can no longer just take the pain. A high-level internecine conflict at the dark heart of the resurgent Russian Empire and an assassin's bullet on an isolated Alpine pass propel him from an apparently run-of-the-mill close-protection task into his most brutal and challenging mission yet. As the body count increases, Stone becomes one of Europe's most wanted.

Out on the ice, polar bears aren't the only natural born killers. Nick Stone is suffering. The two people he cared for most are gone. Thousands of miles away, five ex-servicemen, badly wounded in Afghanistan, are preparing for a trek to the North Pole in an attempt to begin to rebuild their shattered bodies and minds. When Stone is summoned as close protection for the trek by an old SAS officer, he accepts unthinkingly, desperate for the chance to escape his own misery.

Nick Stone is back in London, but if he thought he was home for a break, he's very, very wrong. Backed into a corner by a man he knows he cannot trust, ex-deniable operator Nick Stone strikes a devil's bargain. In exchange for his own safety - a life for a life - Stone is charged with locating someone who doesn't want to be found, currently hiding out in the one of the remotest corners of the UK. And for the first time in a long time, he's not operating alone.
